Re: Converting a number to complex

[Joshua Niehus]

meh, couldn't resist:

import std.stdio, std.conv, std.traits, std.complex;
template isComplex(T)
{
    static if (is(T == Complex!double))
    {
        enum bool isComplex = true;
    }
    else static if (is(T == Complex!float))
    {
        enum bool isComplex = true;
    }
    else static if (is(T == Complex!real))
    {
        enum bool isComplex = true;
    }
    else {
        enum bool isComplex = false;
    }
}

template isComplexOrNumeric(T)
{
    enum bool isComplexOrNumeric = (isComplex!T || isNumeric!T);
}

class Example(T) if (isComplexOrNumeric!T)
{
    T k = to!T(1);
}
